#ConferenceTime Great discussions at #ECSS2026 on the future of #wearables technology and academic #entrepreneurship. Many thanks to Prof. Kamiar Aminian (EPFL), Mina Balniasad (OptiZone), and Dr. Mathieu Falbriard (Bearmind) for sharing valuable insights. Also to Marco Giurgiu for a network update

#ConferenceTime This week, our own Manuel Leitner attended the #CEREPS conference in Münster. Although the focus was on physical education – rather than wearable-based research – it was great to catch up with our advisory board member Manolis Adamakis. Exchanges like these keep a network alive 🫱🏼‍🫲🏽

🌍 Greetings from #ICAMPAM2026 in Knoxville 🇺🇸 Our core group is contributing to the conference: 🎤 Marco joins a symposium on harmonised wearable use 📌 Irina presents our Delphi study – No better place than an international conference full of experts. Great to see so many network members! 👏

✨ Advisory Board Meeting ✨ This week, we shared the progress and discussed future directions for our intitative. A huge thank you to our Advisory Board members for their time, expertise, and valuable feedback 🙏 Stay tuned for our future activities, there is more to come. #Wearables #Network

#ConferenceTime 🤝 Nice meeting at #ISBNPA2026 in Cadíz 🇪🇸 During the poster session of our Delphi study, our own @irinatimm.bsky.social had the chance to connect with Yue Liao and exchange ideas on wearable-based physical behaviour research 🌍 #Wearables #Network

#ConferenceTime ISBNPA 2026 starts today in Cádiz 🇪🇸 @irinatimm.bsky.social and @fiejanis.bsky.social of the Wearable Landscape initiative are on site to connect, exchange ideas, and discuss the latest in wearable-based physical behaviour research. Enjoy the conference everyone! #ISBNPA #Wearables

#ConferenceTime @irinatimm.bsky.social has presented our Delphi study at the Conference of the Arbeitsgemeinschaft für Sportpsychologie in Heidelberg last week – running into contributor Dr. Kristina Klier. Key facts: n=99 participants 84% compliance consensus on 24 items in round two #Wearables

#FactFriday 👉 Did you know? Physical activity, sedentary behaviour, and sleep are mutually exclusive physical behaviours of the same 24-hour day. More time in one behaviour always means less time in another. 💡 Wearable research should focus on the whole 24-h movement behaviour cycle. #Wearables

#FactFriday 👉 Did you know? Wearables can collect millions of data points/day – ~2.6–8.6M at 30–100 Hz, or up to ~25.9M with triaxial sensors. Yet we often reduce this to simple metrics like steps or activity time. 💡 The challenge isn’t collecting data, it’s contextualising it. #Wearables #BigData

📢 New report from the World Health Organization Focus: using wearables for population health monitoring by improving measurement of physical activity & sedentary behaviour for global surveillance. Proud to see the Wearable Landscape initiative contributing to this effort! #Wearables #PublicHealth

#FactFriday 👉 Did you know? Wearable research has shifted from simple cut-point thresholds to machine learning approaches that enable a more nuanced and context-aware analysis of activity patterns. 💬 Are you already using machine learning in your analyses? #Wearables #MachineLearning

#FactFriday ✨ Wearables often perform better in the lab than in real life. Algorithms accuracy can drop substantially in real-world (free-living) conditions — where behavior is more complex and less predictable. 💬 Do you prioritize lab or real-world validation? #Wearables #RealWorldData

#FactFriday 👉 Did you know? The same wearable device can produce very different results depending on where it’s worn. Placement strongly influences how movement is captured, and thus the interpretation of data. 💬 What’s your preferred placement for your research? #Wearables #Accelerometry #Methods

#FactFriday 👉 Did you know? There is an uncountable number of wearable devices on the market – but only a fraction are properly validated. Not all data is equal! Quality mattes – validation is key 🗝️ 💬 Do you check validation studies before using a device? #Wearables #Validation

#FactFriday 👉 Did you know? Accelerometers have been used in research since the 80s/90s — long before fitness trackers. The earliest pedometers date back all the way to the late 19th century. ⏱️ They laid the foundation for today’s wearable-based activity measurement. #Wearables #PhysicalActivity

Exciting News: Our new #Wearables #Database is live! 📊Our team has compiled a systematic, internet-based market analysis of currently available wearable sensors into an interactive database to: - Search for wearables & their features - Get a fast overview of validation studies

📢 New paper out! We calibrated and evaluated MET models for walking and jogging using the Move 4 wearable on the ankle and thigh — with strong agreement vs indirect calorimetry (gold-standard). Great progress for high-resolution energy-expenditure estimation using Move 4 accelerometers 👏 #Wearables

💭How to be #transparent and #fair in large collaborative review processes regarding authorship? We adressed this in our present review (>200 included studies and 24 scientists involved) and developed a weighted scoring system based on the time required for different tasks to fairly credit workloads.
